Not getting the Edited Value of InputText when creating editable DataTable on server

I want to show a dynamic editable dataTable on Page. So, I am creating the dataTable on server and displaying it on page. It is working fine for me.My dataTable have some editable Cells with InputText in it. I have Added HtmlAjaxSupport onChange event of it, and ajax method is getting called properly, but I am not getting the changed value of that InputText in that Ajax call.
